it (till whom it away concern:

. Be it known that I, FREDERICK Caron, a citizen of the United States of America, residing at Joliet, in the county of Will and State of Illinois, have invented certain new and useful Improvements in a ire-Galvanizing Apparatus, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is a perspective view; Fig. 2, a crosssection looking toward one end; Fig. 3, aperspective view of a portion of a pipe lying in a supporting-trough; Figs. 4 and 5, cross-sections of different forms of galvanizing-troughs;

, 5 Fig.6, a rear perspective of a section of the furnace-sides; and Fig. 7, a central longitudt nal view of a portion of a pipe, 0, and a side view of the shoe R, that conducts and supports the wire w. This invention relates to certain improvements in awire-galvanizing apparatus, which improvements I will fully explain in the following specification.

The object of this invention is to so construct the apparatus that it needs very much o dent; also, to render it possible to'repair and replace parts without disturbing the remainingp'arts while the apparatus is in operation.

Referring to the drawings, the furnace consists of the sectional flanged side plates, 'a,

5 lined with fire-brick on their fire-sides, and

saidbrick lining held therein by means of the flanges, as shown in Fig. 6. These side plates so lined are set up as shown in Fig. l, and

held together in position by means of the in- 40 tegral lugsg and bars 1?. Each such section is provided with the draft-holes D and rings 15 t on the top, for the purpose of furnishing means to raise out asection a for repairs,

and be immediately replaced by a new one without disturbing the remaining parts of the furnace or delaying the operation of the apparatus in the least.

In ordinary furnaces of this class the side walls of the furnace are generally built all in one solid continuous wall, so that when itneeds metal. The fuel for kee ra repairs the fires have to be put out and the galvanizing metal necessarily cool oil, and thereby stop further operation. All that difficulty is overcome by constructing the furnace-sides in the removable sections as set 5 forth. 9*

Instead of using a large vat to htldfthe galvanizing material, as is the geuer i practice in apparatuses of this character, t ne galvanizing material is contained within ll-he train of horizontal pipes 0. (Shown in 1.) The metal is melted and poured inat the openings 0 which are located about midway between the ends of said pipes, as'shown iin Fig. 1.

These openings also permit an inspection of the metal at that place, to see if it it in proper working condition. These pipeslre turned up sufficiently at each end, so thall they may be full of metalM between the turned-up ends 0', and prevent it spilling out, as shown in Fig. 7 more particularly. These pipes 0 may be provided immediately under the openings 0 with depressions or troughs n, as shown in Fig. 5, for the purpose of collecting the dross of the galvanizing metal, and rendering it easy to remove the dross by means of aladl'e. These pipes c are supported within the furnace, as shown in'Fig. l, on the beams B supported by legs Ii, and may be constructed of terracotta, fire-clay, or any suitable material of that nature, and they may be, in cross-section, of the forms shown in Figs. 4. and 5, or as shown in the other figures, and, if deemed necessary, lie in a suitable trough, m, for a support, as shown in Fig. 8. l

A lid, A, Fig. l is designed to cover over the furnace and pipes except at their ends, to permit the wire it to be drawn through the pipes c,- or each pipe,'if formed in} the shape of a trough, as shown in Figs. 5 iand 4, can 0 have an individual lid or cover, AZ: In order to prevent the wire 10 from wearing the pipe 0, a shoe, R, shown in Fig. 7, niayi be used to pass the wire through. A thumb-screw, S serves to fasten the shoe 15' the shoe may be removabl In operation, the wire through the pipes c, after fi1led,,as before stated, wi

" 1pc, so that 5 the pipes is supplied between them and the inner sides of the furnace, and the draft-holes D give it sufficient draft. The galvanizing metal is thus kept in a molten state within the pipes, and the wire 10 is drawn through it to galvanize it.

Should a single pipe break or need to be replaced by a new one. the wire 10 can be withdrawn, one end of the pipe raised up to 1)Dl1]l;AOlltc-;Eh6 molten material into a ladle,

wu i e kept molten over a fire, and a laid in to replace the removed 01; s l molten metal poured back into it a minutes, without disturbing any of Should one break and drop its I, I a small portion ofthe galvanbeing used can be lost, and that of the device. 2: described my invention, what 'bing any of the other pipes, or

ing said sections together, as and for the pur- 35 pose set forth.
